Application filed March 11, 19H9. tcl-arial No. 482,759.

To all whom 'it may concern: l

Be it known that I, nigitnnli. SWAHN, a subject of the King of Sweden,residing at Brooklyn, in the county ofKings and State of New York, haveinvented certain new `imifterlfnlly described and claimed, and

illustrated in the .aco inpanying drawings, in which-.-- l

Figure It is a. side ele tation of a preferred embodiment of theinvention, certain parts being broken away; Fig.` 2 is an enlargedlongitiidinalvertical section of the rear portion' ofthe truck and theprincipal parts oi the gun Fig. 3 is a planview of the gun casing andbreech mechanism, a portion of the cover being broken away; Fig. el is aface view -ot the. breech, thebreecli block be ing elevated; Fig. a rearface View of the breech block in diagram; Fig. t1 is a. de-A tail of themuzzle of one of the gun barrels;

. Fig. 7 is a detail of the breech mechanism and. firing devices; Fig. 8is a detail pei'- speetive ot' the projectile sheath; Fig. 9 is aperspective view indicating a cartridge clip; Fig. l() is a View of theforni of cartridgc clip usedat the end of the breech member, and Fig. llis a `fragment of the' wiring for the tiringdcvice. f

Throughout the `following detail description and on the several' figuresof the drawings similar parts are referred to by like rete-rencecharacters.

Referring to the drawings by reference (-.liaractei's the invention isshown as applied to a truck or carriage l0 of any suitable constructionadapting it for convenient transportation and manipulation. The frame 1lis shown as being supported upon front wheels 1Q and a. pair of rearWheels i3, the intermediate portion of the frame being dropped'to form aplatform le upon which ainoperator stands during firing operation.',l`he. .dev iceinay be ldrawn' by hand or by horses.I and' is providedpreferably with a seal. 15. fl'he front'portion of the frame and front,axle areso related that the front'. wheels may turn fully around underythe traine `for ease ot' turning and guiding.

The gun casing 1G is supported upon a horizontal axis l? above the rearaxle 18 of the carriage, and is adjustable with respect to saidaxis bymeans of a rod 20 pivotally connectedto the casing 16 atv 2l and havingthreaded engagement witha nutl 22 i to which is connected an operatinghand wheel 23, the said nut 22 being pivoted atvQd in the. frame 25,whereby the rod 2O may oscillate to accommodate the pivotal move-- mentsof the casing on the axis 17. i By the means just .described the guneasingv may be adjusted so as to train 'the guns in the mannerdescribed. The casing may be constructed of any suitable size, form, ormaf terials.v i v lWitliiii the casing 1G and extending through'thesaine from frontto rear are a series ot gun barrels 26. is shown saidcasing is segmental in planl view and the gun barrels contained thereinarc ariangedin the form ot a t'an or radiating in a flaring shapev inorder that the scope ot' the gun may be very broad. As indicated inFigs. 2 and 4 the gun barrels are arranged in a plurality of rows orseriesr` the breech or rear ends of the same are. comparatively closetogether and it is my intention to employ-in Connection with the Vgun apeculiar arrangement ot' ammunition. llach gun barrel 26 is secured inany suitable manner as by screw threads into the breech 27 and itsniuzzle.

projects through the easing member'QS and isproteeted on the outsideot'the saine by means ot afivasher 29 having a countersunk hole 25)',the extreme end 26 boing upset into said countcrsink. As indicated inFig. 4 the breech openings are arranged in rows or groups of tour each,cach group being slightly inclined from the vertical. ln each ot' thcscgroups itv is intended to insert a series of cartridges carried by aysingle clip indicated at 30. yit each end oi the 'face of the breechthere may be left one or more single openings which may be filled by theuse ot a clip 3i bearing a single cartridge.

lt is the intention that the ammunition will be carried in cases fromwhich the operator or operators may remove the same with rapidity andslip them into the gun. -For thel purpose oir/extracting the emptyshells Sti down the Lnine the eiips 30 with the Sheilal therein will bequickly extracted from the gun. floiih rods engage the clips 3() while ionl \v one oi them wlli engage the ehps 31.
